Millet (M) and banana peel (Bp) possess significant nutritional qualities and have been shown to reduce obesity resulting from a high-fat diet (HFD). The present research assessed the effect of millet flour and banana peel mixtures on lipid profiles, liver and kidney functions, and characterized food products derived from these mixtures. Thirty-five male albino rats were allocated into five groups for a biochemical analysis. The control group (n = 7) received a basal diet, while the remaining 28 rats were fed a high-fat diet (HFD) for 8 weeks to induce obesity. These rats were then separated into four sub-groups (n = 7 each): sub-group 1 as the positive control (+ve) receiving only HFD, while sub-groups 2, 3, and 4 were administered HFD supplemented with millet flour and banana peel mixtures (M90+Bp10 %, M80+Bp20 %, and M70+Bp30 %), respectively for an additional 8 weeks. The chemical composition analysis showed that banana peel (Bp) has higher levels of fat, ash, fiber, magnesium, and potassium, while millet flour is richer in carbohydrates. Bp also had superior antioxidant activity and total phenol content (13.32 % and 10.54 mg/100g) compared to millet flour (3.75 % and 4.55 mg/100g). Biochemical tests on the HFD plus (M70+Bp30 %) group revealed improved lipid profiles, leptin, antioxidant enzymes, and kidney and liver functions. Glucose levels were higher in the HFD group (137.33 mg/dl) than in the control (85.70 mg/dl), but these levels were reduced with millet and banana peel treatment. The histology of liver tissues confirmed the biochemical results. Sensory evaluation of pancakes and toast from the (M70+Bp30 %) mixture by forty panelists showed high acceptability, aligning with the biochemical outcomes. This study suggests that a banana peel and millet flour mixture could help reduce obesity.
小米（M）和香蕉皮（Bp）具有显著的营养特性，并且已被证明能减轻高脂饮食（HFD）导致的肥胖。本研究评估了小米粉和香蕉皮混合物对脂质谱、肝脏和肾脏功能的影响，并对由这些混合物制成的食品进行了特性分析。将35只雄性白化大鼠分为五组进行生化分析。对照组（n = 7）给予基础饮食，而其余28只大鼠喂食高脂饮食8周以诱导肥胖。然后将这些大鼠分为四个亚组（每组n = 7）：亚组1作为阳性对照（+ve），仅接受高脂饮食，而亚组2、3和4分别给予补充了小米粉和香蕉皮混合物（M90+Bp10%、M80+Bp20%和M70+Bp30%）的高脂饮食，持续另外8周。化学成分分析表明，香蕉皮（Bp）的脂肪、灰分、纤维、镁和钾含量较高，而小米粉的碳水化合物含量更丰富。与小米粉（3.75%和4.55mg/100g）相比，Bp还具有更高的抗氧化活性和总酚含量（13.32%和10.54mg/100g）。对高脂饮食加（M70+Bp30%）组的生化测试显示，脂质谱、瘦素、抗氧化酶以及肾脏和肝脏功能均有所改善。高脂饮食组的血糖水平（137.33mg/dl）高于对照组（85.70mg/dl），但通过小米和香蕉皮处理后这些水平降低了。肝脏组织的组织学检查证实了生化结果。由40名评判员对（M70+Bp30%）混合物制成的煎饼和烤面包进行感官评价，结果显示接受度很高，这与生化结果一致。本研究表明，香蕉皮和小米粉混合物可能有助于减轻肥胖。
